Application filed February 24, 1912.

To all ivf/om it may concern: Be it known that l, JAMES H. SAeER, citirfen of the United States, and resident of -liochesten in the county of Monroe and citate oi' Kew York, have invented certain new and useful Improvements in Automobile-Bumpers, oi' which the following is a specification.

This invention relates to automobilebumpers of the type in which a horizontal ward extremities ot the side frame-members oi' the automobile.

rl`he object ot' the present invention is to produce a simple and rigid construction by which the bumper, when applied to automobiles of various designs, may have its parts so positioned. in every case, as most effectually,l to resist the strain of a collision ,in the connections between the sleeve 6 and against the bumper-bar.

To this end the invention consists in an arrangement by which the forwardlyextending members or bar-supports are connected with the base-members by means of coperating convex and concave portions permitting relative angular adjustment of these parts in verticalfplanes, whereby the supports may be arranged in any position either horizontal or inclinechwhich may be found most effective for the purpose in question.

ln the drawings z-Figure 1 is a sideelevation of a bumper embodying the present invention, as applied to an automobileframe. Fig. 2 is a vertical section through .one of the supports and the base-member on which it is mounted; and Fig. 3 is a sectio on the line 3--3 in Fig. 2.

rl`he general construction of the illustrated bumper is not novel. rthe bumper comprises the usual horizontal cross-bar 1 with lmokwardly-curved extremities, which is adapted to be carried in iront of the front-wheels ot the automobile and to be supported vby means connecting it with the forward extremities 5 of the side trame- Specication of Letters Patent.

members of the vehicle. The bumper-bar is clamped in heads 6 on the forward ends of stems 7, `which are slidingly mounted in sleeves S. A compression-spring 9 is carried in each sleeve 8, and a rod 10 is screwed into the rear end of the stem 7 and passes through an opening in the rear end of the sleeve, being provided with a square head 11 by which it may be screwed into the stem, and which acts as a stop to retaiuthe stem in .the sleeve against the pressure of the spring.

rlyhe general form of the illustrated basemember is similar to that disclosed in my pendingapplication, Serial No. 656,013,

i-led October 21, 1911. As disclosed in said the side :trame 5 oit the automobile and overhang its forward extremity, one of these webs being provided with a lug 13, which Vprojects beneath the upper web of the frame-member and is provided with-a setscrew la, by which the base-member may lbe clamped to this web, thus fixing it in place upon the frame. l

The present invention resides particularly the base-member 12. The forward extremity of the base-member is formed upon a circular convex curve, and the rear extremity of the spring-sleeve has a corresponding segmental form, being provided with upwardlyand downwardly-projecting lugs 15 curved concavely to fit against the surface 16 of the base-member.` rthese lugs areslotted to receive set-screws 17, which enter bosses formed in the base-member. When these set-screws xare loosened the segmental portion of the spring-sleeve may slide upwardly or downwardly upon the surface 16, thus changing the angular osition of the barsupport as a whole, w ile still retaining a firm seat upon the base-member. rllhe parts are clamped in adjusted position by means of the set-screws 17.

The pivotal arran ement just described, while readily adjusta le, is rigid and 'secure against movement by any of the shocks encountered by the bumper, owing to the extensive curved surfaces which are in engagement between the supports and the basemembers, and the device thus has substantially the rigidity et the usual integral Ycongas ILE

struction, whilel being readily adaptable, Without modication in its design, yto automobiles having frame-members of various degrees of curvaturevat their forward extremities.

As shown in Fig. 2; the forward portionof the base-member is out away between the bosses 18, thus aording free play for the rod within the base-member; when the bumper is subjected to a shock by which thev spring 9 is compressed. l rlhe square head 11,

vby its engagement with the flat lateral webs of the base-member, fixes the rod against ro tation, and thus prevents it from unscrewing from thestem 7 when the parts are in assembled position.

My invention is not limited to the embodiment thereof hereinbefore described and illustrated-in the accompanying drawings,y

but maybe embodied in various other forms within the nature of the invention as it is defined in the following claims.

1. ln an automobile bumper,.the combination of a base-member formed to seat upon the forward extremity-of the side framemember ofan automobile and provided with a hollow forwardly-convex portion and an opening in the front-wall thereof; a` sleeve having a rear extremity fitting against the convex surface of said front-wall and covering said opening; means for fixing the sleeve adjustably upon said surface, whereby vertical angular adjustment of the sleeve is permitted; a slide-member mounted in the sleeve and adapted, at its forward end, to support abumper-bar or the like, the rear-end of the slide-member projecting through the rear-end of the sleeve. and into the opening in the base-member, and the hollow forwardly-projecting portion ofthe base-member affording space in which the slide-member may move when it is forced rearwardly; and a spring interposed between the sleeve and the slide-rnember and tending to hold the latter in its normal forward position within` the sleeve.

2. An automobile bumper having, in oombination, a transverse ybumper-har, hollow base-members formedxto seat upon the forward extremities of the side frame-members of an automobile and provided. at their fo-rward extremities, with ciroularly-curved surfaces and with central openings therein. supports extending forwardly from thebasevmembers and carrying the bumper-bar, each
